Best NFL Betting Promos Explained

Every option from the NFL betting promos below is for new customers only, and what you can claim depends on the state you're betting from. Our sportsbooks by state page lets you know what offers are active in your location, and we break down the key offers below. Be sure to check the NFL injury report before making any bets.

1. Fanatics Sportsbook

Fanatics doesn't hand you one lump bonus. Sign up with the Fanatics Sportsbook promo code ACTION26 and Fanatics matches your qualifying wager in FanCash every day for 10 straight days, up to $100 a day and $1,000 total. A bet on Bills vs. Rams tonight can be day one of that run.

If you'd rather get paid without the daily routine, code ACTION350 turns a $20 bet into $350 in FanCash, paid out as $50 a day over seven days. New York has its own path: 10 profit boost tokens instead of a match. Pick the version that fits how often you actually plan to bet.

2. BetMGM

The BetMGM bonus code TOPACTION backs your first bet with up to $1,500 in bonus bets if it loses. That's a good fit for Monday night if you like the Bills as a road dog or want a piece of a 54.5 total without fully trusting it.

BetMGM also runs two other versions depending on where you live: up to $1,000 in No Sweat Tokens over 10 days, or a $10 bet-and-get that pays $150 in bonus bets if you win in Michigan, New Jersey, Pennsylvania and West Virginia.

3. bet365

There's no catch to work around here. Bet $10 on Bills vs. Rams with the bet365 bonus code offer, and bet365 pays $200 in bonus bets whether that bet wins or loses. If you don't want to sweat a result just to collect a bonus, this is the easiest offer on the list.

A few states get a different version. Indiana's bet-and-get pays $365, New Jersey, Michigan and Pennsylvania add 50 casino spins, and Illinois, Tennessee and West Virginia get a $150 version. bet365 also offers a First Bet Safety Net up to $1,000 instead.

4. DraftKings Sportsbook

DraftKings just upgraded its welcome offer. The DraftKings promo code offer now turns a $5 bet into $200 in bonus bets, paid as $50 every seven days over 21 days, plus three months of NBA League Pass with the NBA season about to start.

It's still the cheapest way in on this list. Put $5 on the Rams, the Bills or anything on the Monday night prop board, and the bonus bets start coming regardless of the result. The League Pass code has to be redeemed by Dec. 19, and the subscription renews monthly after the free three months unless you cancel.

5. FanDuel Sportsbook

The FanDuel promo code offer is built for bettors who'll be around all week. Bet at least $5 for five straight days and FanDuel pays $50 in bonus bets each day, up to $250. Tonight's game can be day one, and Thursday Night Football lands inside the window.

It's live in 25 states, which makes it one of the most widely available NFL betting promos for Monday night.

6. theScore Bet

The theScore Bet promo code ACTNEWS gets you a first bet reset worth up to $1,000. If your first bet loses, theScore Bet gives the stake back in bonus bets.

In Michigan, New Jersey, Pennsylvania and West Virginia, the same code unlocks a $10 bet-and-get that pays $100 in bonus bets if your bet wins.

7. betPARX

betPARX is Pennsylvania only, but PA bettors get a choice. Use betParx promo code TANBONUS and pick either $50 in bonus bets for a $25 bet or a single 200% profit boost when you register.

The profit boost is the better fit if you have one Monday night bet you like a lot.

8. Hard Rock Bet

New users in Michigan and New Jersey can turn a $5 bet into $500 in No Sweat Bets with the Hard Rock Bet promo code offer.

It's one of the newest offers on this list, and the No Sweat structure gives you a cushion on bets you place after tonight too.

9. BetRivers

The BetRivers bonus code offer gives you a second chance if your first bet loses. How much comes back depends on your state.

Michigan and Pennsylvania bettors can get up to $500 back, New Jersey tops out at $250 and West Virginia at $100.

10. Borgata

New Jersey bettors who sign up with code Borgata bonus code ACTION and bet $20 get $100 in bonus bets.

Nothing has to win for the bonus to land, so it's one of the simplest NFL betting promos in New Jersey tonight.

Trade Monday Night Football on Prediction Markets

Live in a state without legal sports betting? Prediction market apps let you buy and sell contracts tied to game outcomes instead of placing a traditional bet. Sign up with one or both of these NFL prediction market promos, and you have a chance to trade on Monday Night Football.

Contract prices move between 1¢ and 99¢ based on how the market rates each outcome, and these CFTC-regulated platforms are available in many states where DraftKings, FanDuel and other sportsbooks aren't, including California and Texas.

1. Polymarket

New users who deposit $10 with the Polymarket promo code ACTION get a $25 trading bonus.

Polymarket lists contracts on the Bills vs. Rams winner, spread and total, and you can sell a position before the game ends.

2. Kalshi

The Kalshi promo code ACTION55 gets new users $55 when they sign up and trade $25.

Your trades don't have to win for the $55 to count. Hit the $25 trading minimum and meet the requirements in Kalshi's terms, and the bonus is yours. Kalshi has full margin and total ladders for Monday night, so you can pick the exact Rams or Bills number you want.
